History of the Peloponnesian War

While they were thus blockaded from the sea and plundered by land, some of the citizens undertook to bring the city over to the Athenians. Appraised of this the authorities took no action themselves, but brought Astyochus, the admiral, from Erythrae, with four ships that he had with him, and considered how they could most quietly, either by taking hostages or by some other means, put an end to the conspiracy.

While the Chians were thus engaged, a thousand Athenian heavy infantry and fifteen hundred Argives (five hundred of whom were light troops furnished with armour by the Athenians), and one thousand of the allies, towards the close of the same summer sailed from Athens in forty-eight ships, some of which were transports, under the command of Phrynichus, Onomacles, and Scironides, and putting in to Samos crossed over and encamped at Miletus.

Upon this the Milesians came out to the number of eight hundred heavy infantry, with the Peloponnesians who had come with Chalcideus, and some foreign mercenaries of Tissaphernes, Tissaphernes himself and his cavalry, and engaged the Athenians and their allies.
